发明名称 THIN FILM MAGNETIC HEAD
摘要 PROBLEM TO BE SOLVED: To provide a thin-film magnetic head capable of surely and easily interconnecting first and second coils formed up and down across a magnetic pole layer electrically, and maintaining high insulation between the second coil and the magnetic pole layer. SOLUTION: A lifting layer 72 is formed on coil insulating layers 36 formed on both sides of a layered body 62 for regulating a track width in a medium facing surface, and the upper surface 72a of the lifting layer 72 is electrically connected to the end of the second coil piece 56 in a track width direction. Thus, the end of the second coil piece 56 is lifted more than conventionally by the formation of the lifting layer 72. As a result, the pattern of the second coil piece 56 is highly accurately formed, and the end of the second coil piece 56 is electrically connected to the upper surface of the lifting layer 72 surely and easily. Moreover, high insulation is maintained between the second coil piece 56 and the layered body 62. COPYRIGHT: (C)2005,JPO&NCIPI
